XDB502 mndandanda mkulu-kutentha kugonjetsedwa submersible madzi mlingo transmitter ndi zothandiza madzi mlingo chida ndi kapangidwe wapadera. Mosiyana ndi ma transmitters amtundu wa submersible fluid, amagwiritsa ntchito sensor yomwe siyimalumikizana mwachindunji ndi sing'anga yoyezera. M'malo mwake, imatumiza kusintha kwamphamvu kudzera mumlengalenga. Kuphatikizika kwa chubu chowongolera kuthamanga kumalepheretsa kutsekeka kwa sensa ndi dzimbiri, kukulitsa moyo wa sensor. Kapangidwe kameneka kamapangitsa kukhala koyenera kwambiri kuyeza kutentha kwakukulu ndi ntchito zonyansa.
